with all the different color wire and electrical components needed to be hooked up.
It is very important to have both the engine wiring diagram and vehicle wiring diagram.
A little research goes a long way in this area; not having these wiring diagrams will make it almost, if not completely, impossible to do this swap.
One place to look for engine wiring diagrams is LT1 swap. This website was invaluable to me for wiring my LS1 swap. LT1 swap also has information on LT1,LS1,LSX, and much more.
So take a little time and do your homework, it will make your project much easier.
